US and NATO should completely withdraw from all combat and peacekeeping roles in Afghanistan.

Pros

Cons

The war in Afghanistan cannot be won; it is best for Western forces to admit defeat and withdraw.

Western forces are harming the country more than they are helping to protect and rebuild it.

The costs to Western nations of the war in Afghanistan are far too high.

The Afghanistan war is unjust.

A reduction in influence of Western nations in Afghanistan will be accompanied by a rise in Russian and Chinese influence in the country, creating a new power balance that will be even worse for the country.

A withdrawal of forces would result in infighting between various government, military and militia factions, possibly resulting in an all-out civil war.

The West ought to combat terrorism around the world.

The US and NATO have a moral responsibility to assist in the reconstruction and development of Afghanistan.

President Trump's new Afghanistan policy has potential to succeed. Western forces should not disengage from Afghanistan until the policy is seen to its fruition.

A complete withdrawal of all forces would create a power vacuum that the various terrorist organisations in Afghanistan, including the Taliban, will exploit, possibly leading to their rule in the country.
